In December 2022, based on the assessment of new evidence, the World Health Organization (WHO) updated its guidelines for the treatment of drug-resistant tuberculosis (TB). The evaluation of both, these recommendations, and the latest study data, makes it necessary to update the existing guidelines on the treatment of at least rifampicin-resistant tuberculosis for the German-speaking region, hereby replacing the respective chapters. A shortened MDR-TB treatment of at least 6 month using the fixed and non-modifiable drug combination of bedaquiline, pretomanid, linezolid, and moxifloxacin (BPaLM) is now also recommended for Germany, Austria, and Switzerland under certain conditions. This recommendation applies to TB cases with proven rifampicin resistance, including rifampicin monoresistance. For treatment of pre-extensively drug resistant TB (pre-XDR-TB), an individualized treatment for 18 months adjusted to resistance data continues to be the primary recommendation. The non-modifiable drug combination of bedaquiline, pretomanid, and linezolid (BPaL) may be used alternatively in pre-XDR TB if all prerequisites are met. The necessary prerequisites for the use of BPaLM and BPaL are presented in this amendment to the S2k guideline for 'Tuberculosis in adulthood'., Competing Interests: Informationen zu Interessenkonflikten finden Sie auf den Seiten der AWMF (http://www.awmf.org/leitlinien/awmf-regelwerk.html)., (Thieme.

According to the annual global reports from the Word Health Organization (WHO), children under 15 years of age represent 11% of all cases of tuberculosis (TB) globally. Nearly 50% of these cases are children below 5 years old. This continuing medical education (CME) article provides an overview of the current recommendations and innovations based on the revised WHO guidelines on TB management in children and adolescents published in 2022., (© The Author(s), under exclusive licence to Springer Medizin Verlag GmbH, ein Teil von Springer Nature 2023.)

In Germany tuberculosis is a rare disease and usually well treatable. Worldwide it is one of the most common infectious diseases with approximately 10 million new cases every year. Even with low incidences in Germany, tuberculosis is an important differential diagnosis especially due to international developments and migration movements. With a decreasing experience there's a continuous demand on accurate and up-to-date information. This guideline covers all aspects of microbiological diagnostics, basic principles of standard therapy, treatment of extrapulmonary tuberculosis, management of side effects, special features of diagnosis and treatment of resistant tuberculosis, and treatment in TB-HIV coinfection. Also, it explains when treatment in specialized centers is required, aspects of care and legal regulations and the diagnosis and preventive therapy of latent tuberculosis infection. The update of the S2k guideline "Tuberculosis in Adults" is intended to serve as a guideline for prevention, diagnosis, and treatment of tuberculosis for all those involved in tuberculosis care and to help meet the current challenges in dealing with tuberculosis in Germany., Competing Interests: Eine Übersicht der Interessenkonflikte findet sich im Internet unter http://awmf.org; AWMF-Registriernummer 020-019, (Thieme.

Recently, epidemiological data shows an increase of childhood tuberculosis in Germany. In addition to this, drug resistant tuberculosis becomes more frequent. Therefore, diagnosis, prevention and therapy in childhood and adolescence remain a challenge. Adult guidelines do not work for children, as there are age specific differences in manifestation, risk of progression and diagnostic as well as therapeutic pathways.The German Society for Pediatric Infectious Diseases (DGPI) has initiated a consensus-based (S2k) process and completed a paediatric guideline in order to improve and standardize care for children and adolescents with tuberculosis exposure, infection or disease.Updated dosage recommendations take age dependant pharmacokinetics in the treatment of drug sensitive but also drug resistant tuberculosis in account. In addition to this, there is a detailed chapter on perinatal exposure and disease as well as extrapulmonary manifestations., Competing Interests: Interessenkonflikt: Siehe Interessenkonflikterklärung auf www.awmf.org., (© Georg Thieme Verlag KG Stuttgart · New York.)

Since 2015 a significant increase in tuberculosis cases is notified in Germany, mostly due to rising numbers of migrants connected to the recent refugee crisis. Because of the low incidence in previous years, knowledge on tuberculosis is more and more limited to specialized centers. However, lung specialist and healthcare workers of other fields have contact to an increasing number of tuberculosis patients. In this situation, guidance for the management of standard therapy and especially for uncommon situations will be essential. This new guideline on tuberculosis in adults gives recommendations on diagnosis, treatment, prevention and prophylaxis. It provides a comprehensive overview over the current knowledge, adapted to the specific situation in Germany. The German Central Committee against Tuberculosis (DZK e. V.) realized this guideline on behalf of the German Respiratory Society (DGP). A specific guideline for tuberculosis in the pediatrics field will be published separately. Compared to the former recommendations of the year 2012, microbiological diagnostics and therapeutic drug management were given own sections. Chapters about the treatment of drug-resistant tuberculosis, tuberculosis in people living with HIV and pharmacological management were extended. This revised guideline aims to be a useful tool for practitioners and other health care providers to deal with the recent challenges of tuberculosis treatment in Germany., Competing Interests: Interessenkonflikt: Siehe Interessenkonflikterklärung auf www.awmf.org, (© Georg Thieme Verlag KG Stuttgart · New York.)

Protocols recommended in the USA and Germany for the postnatal treatment of congenital toxoplasmosis are mainly based on the National Collaborative Chicago-based Congenital Toxoplasmosis Study that calls for daily administration of pyrimethamine in combination with sulfadiazine for several months, then 3 times a week. The recommended total duration of treatment is 12 months. This scheme necessitates frequent white blood cell counts that often result in the discontinuation of treatment because of severe neutropenia even with the concomitant administration of folinic acid. In contrast, the administration of pyrimethamine with sulfadoxine every 2 weeks for 2 years, as used by a referral centre in Toulouse, France, is associated with less toxicity. The efficacy may even be improved, as judged by the rate of new chorioretinal lesions. In the absence of larger randomised studies the Toulouse protocol appears to have several advantages when a decision has to be made to treat infants with congenital toxoplasmosis., (© Georg Thieme Verlag KG Stuttgart · New York.)

The HIV-infection in adults or children and adolescent differs substantially. Differences include the mode of infection, viral dynamics facing a developing immune system and the clinical course of the infection. In addition to the virological, immunological and epidemiological aspects the psychosocial situation is also very different. The above aspects and the decreased number of antiretroviral substances underline the need for specific guidelines for HIV-therapy in children and adolescents. The German Pediatric Working group AIDS (PAAD) has formulated this guideline in 2011 based on new study results, changes in international recommendations and newly available drugs., (© Georg Thieme Verlag KG Stuttgart · New York.)

The natural course of mostly perinatally acquired childhood HIV infection shows some special characteristics. Compared to adults the initial viral load is higher, persists for a longer period of time and without antiretroviral therapy up to 20% of infected children develop AIDS within the first year of life. It is therefore desirable to stop disease progression before an irreversible deterioration of the immune system has occurred by initiating early antiretroviral therapy. The choice of antiretroviral agents is difficult because data from adult studies cannot be directly applied to infants and data on antiretroviral therapy in pediatric patients are limited. The current national and international guidelines for antiretroviral therapy in perinatally acquired HIV infection are discussed.
